Highly Efficient and Novel Method for Synthesis of 1,3,5-Triarylbenzenes from Acetophenones

Abstract

Heteropolyacid–phosphomolybdic acid has been found to be an efficient and recyclable catalyst for cyclotrimerization of acetophenones into 1,3,5-triarylbenzenes in good yields.

Keywords:

• Acetophenones
• heteropolyacid
• 1,3,5-triarylbenzenes
